Answer 6

\(\frac{14}{3}+\frac{6}{17}+\frac{28}{17}\)

\(=\frac{14}{3}+\left(\frac{6}{17}+\frac{28}{17}\right)\)

\(=\frac{14}{3}+\frac{34}{17}=\frac{14}{3}+2\)

\(=\frac{14}{3}+\frac{6}{3}=\frac{20}{3}\)

Answer 7

TL

\(\frac{14}{3}+\frac{6}{17}+\frac{28}{17}\)

= \(\frac{14}{3}+\frac{34}{17}\)

= \(\frac{14}{3}+2\)

= \(\frac{14}{3}+\frac{6}{3}\)

= \(\frac{20}{3}\)
